Audionet DNP

The Birth of a New Reference

Audionet’s new DNP (Digital Network Preamplifier) offers a new standard in combining world class tone, dynamics and reference class sound staging with access to a multitude of digital formats, turning digital music data into a captivating listening experiences. The Audionet DNP is a high potential preamplifier that competes favorably with the world’s best, including our own, all analog Audionet PRE G2. The Audionet DNP is capable of handling both coarse and fine dynamic with outstanding musical exactness and finesse while paying special attention to imaging as well as room correction. In combination with Audionet’s new reference external power supply, the EPX, the DNP reaches new levels of performance, featuring the usual Audionet qualities of presenting music as realistic as possible and free from grain, distortion or coloration, while offering also rarely found level of convenience and customization in integrating signals from computers, servers, HDD, USB sticks and streaming from the internet.

The Audionet DNP is the first preamplifier which can be fully integrated into a network and controlled completely by Windows, Linux or Mac computers. Users worldwide noticed the outstanding ease of use, making programming the DNP a breeze. Our in-house developed software RCP (Audionet RCP – Audionet Remote Control Point) allows the user to organize complex functions and settings effortlessly through a GUI (graphic user interface).

Additionally intuitive and powerful apps are available, which interfaces with all tablet PCs

and smart phones, including all members of the Android and iOS operating systems

integration into home automation systems. At long last it can also be controlled in the classic way with the Audionet System Remote Control.

The Audionet DNP is the very first stereo preamplifier that is equipped with an ultra precise delay, bass, and equalization management, allowing for very nuanced balance adjustment while preserving the coherence of the music. The Audionet DNP allows near unlimited options to adjust the music reproduction, setting a new standard in high quality customizable music reproduction systems. To accomplish this, we have further enhanced our proven and acclaimed digital filter technology and integrated it into the DNP. A pair of subwoofers may be integrated, which are separately adjustable in all parameters. Room influences and tonal challenges and problems can be efficiently corrected. Speaker arrangements can be optimized for every possible listening situation. Joined withAudionet’s room analysis software, CARMA, which captures and analyzes the acoustical behavior and properties of the room, the Audionet DNP is now able to perform professional grade room compensation and correction for the passionate amateur and expert.

The Audionet DNP offers a wealth of features. It receives internet and FM radio, has a USB audio and a digital USB-A interface, can be upgraded with a high-class phono preamp, may be integrated into any home cinema due to its bypass mode and has an excellent onboard A/D converter which can be used for the high-class digitalisation of all analogue sound sources. The inputs can be named freely and different input levels matched. Connected via Audionet Link, other Audionet devices can also benefit from a remote turn-on. A trigger output can be used to control active speakers. And it has even an automatic mains phase recognition.

Maximal connectivity is provided by thirteen (13!) digital inputs, and five analogue inputs; digital ports include WLAN, LAN, USB Audio, and S/PDIF, electrical and optical. In analogue, the DNP features five stereo inputs, four coaxial, and one balanced. In total, the Audionet DNP is capable of powering up to two subwoofers and six power amplifiers.

Optionally, the DNP can be extended with our high-quality phono preamplifier board. Audionets DNP is compatible with the external precision mains adaptor EPX. Please note: the external precision mains adaptor EPS G2 is not suitable for the DNP, please use the EPX instead!

Construction

The DNP’s development and realization combines cutting edge circuit design with Audionet’s eighteen years of experience in digital and analogue technology. More than 5000 individual components ensure accurate signal processing. Isolated and autonomous power supplies for digital and analogue sections further reduce power source-related imperfections.

High-performance processors working in combination with Audionet’s proprietary software for digital signal processing manage the digital signal processing of the Audionet DNP.

Equalizer, Delay- and Bass-Management

The DNP’s double precision bass management uses 48-bit resolution at all sampling frequencies, enabling the most accurate reproduction of even the lowest frequencies. The bass manager offers freely selectable cutoff frequencies, filter Q factors, and subwoofer phases; thus enabling integration of up to two subwoofers into the network, and are configurable into multi-room outputs.

The digital parametric equalizer uses 5 Minimum Phase Equalizers (MPE), for main channel and subwoofer outputs. Each MPE is configurable in filter type, frequency, gain, and Q factor within an unusually wide adjustment range, allowing the effective optimization of all parameters and compensation of less than ideal room characteristics or acoustical problems. The delay manager allows for a range of up to 7 meters, automatically calculating delay times in relationship to the setup and speaker distances while allowing phase control of each subwoofer.

Signal Processing

In order to optimize the D/A conversion, Audionet’s engineers pursued the uncompromising reduction and elimination of jitter, resulting in a highly exact, musical and solid sound image, stage and depth. To this end, we have developed Audionet’s Intelligent Sampling Technology, which performs with stellar results the analogue signal recovery from the digital bit stream. Audio data is routed through a two-stage filtering and decoupling procedure.

First, the input data is filtered with Audionet’s proprietary software using a powerful signal processor and up sampled synchronously, through filters designed for optimal transient and frequency response. At the next stage, the optimized data is then resolved through an asynchronous up sampling procedure at 192kHz/24bit, allowing the complete isolation from any potential jitter originating from the input clock. The resulting audio data is then passed to two high-performance converters, which are clocked by dedicated ultra high precision quartz crystals and individually processed per channel into analogue signals. This method ensures that jitter faults are eliminated – completely lossless – in the analogue signal to the highest degree, resulting in unmatched clarity, room depth, and stage imaging. In addition, power flux interferences are avoided by powering the digital section of the Audionet DNP entirely separately from the analogue section.
